The Melbourne overlays that catch KDR most often
A knockdown rebuild in Melbourne almost always involves at least one overlay on the planning scheme, and those overlays are what drive most of the "surprise" cost between an initial quote and a signed contract. The most common: Heritage Overlay (HO), Neighbourhood Character Overlay (NCO), Significant Landscape Overlay (SLO) and Vegetation Protection Overlay (VPO).
Every Melbourne council publishes its own local planning scheme via the Planning Victoria portal. Before you request a KDR quote, look up your parcel on VicPlan (linked below), note the overlays that apply, and ask any builder you shortlist how each one affects their design fee and their timeline. A responsible Melbourne builder will answer in specifics; a bad one will hand-wave.
- Look up your parcel on VicPlan (free, official Planning Victoria tool)
- Note every overlay code that applies (HO, NCO, SLO, VPO, DDO...)
- Read the council's local schedule for each overlay
- Ask your builder to price the design response to each overlay separately
- Factor an extra 8-16 weeks for the permit path where a heritage overlay applies
Demolition in Melbourne: what actually happens
The demolition line item on a Melbourne KDR tender is usually more complicated than in a similar Adelaide project. Two drivers: pre-1990 homes commonly carry asbestos which triggers a licenced-removal process under WorkSafe Victoria, and Melbourne's Environment Protection Authority landfill levy is meaningfully higher than the SA equivalent per tonne of construction and demolition waste.
A responsible Melbourne demolisher will provide a written asbestos assessment, a waste management plan, and a completion certificate. If your builder subcontracts demolition, ask to see the sub’s VBA registration for demolition and their environmental compliance history. Both are on public registers.
Permit path: council by council
BuildPilot has published nine Melbourne LGA guides so far (Melbourne, Yarra, Port Phillip, Stonnington, Boroondara, Glen Eira, Whitehorse, Bayside, Whittlesea). Each covers the local planning permit path, the overlays that apply, typical processing timeframes and the council's contact details. The nine at /vic cover most of the KDR volume in inner and middle Melbourne today. More councils land as the Victoria edition rolls out.
Frequently asked
Do I need a planning permit for a KDR in Melbourne?+
It depends on the overlays that apply to your specific parcel. Some blocks require a planning permit for demolition itself under a heritage overlay; others only require a building permit. VicPlan will tell you in about 30 seconds - link below.
How much does demolition cost in Melbourne?+
The all-in demolition line item in Melbourne is driven by three variables: house size, asbestos presence, and site access. A single storey brick veneer on a straightforward site sits at one end of the range; a heritage weatherboard with confirmed asbestos on a tight inner-city block sits at the other. A responsible demolisher will provide a written quote after a site inspection, not a phone estimate.
Can I keep the slab and just rebuild on top?+
Rarely worth it in Melbourne KDRs, though technically possible. The existing slab was designed for a specific footprint and load; your new home almost never lines up. Most Melbourne builders will price a full slab replacement as the default, and quote the "reuse" case only after a structural engineer signs off - which is another cost.
How long does a Melbourne KDR take end to end?+
The rough shape: 6-16 weeks for design and council approval (longer with heritage or neighbourhood character overlays), 2-4 weeks for demolition and site prep, then 8-14 months for construction depending on home size and builder throughput. Every step depends on your council, your overlays and your builder - none of these numbers is a promise.
Do BuildPilot's Melbourne KDR figures apply state-wide?+
The overlay framework and demolition regs are state-wide (VBA, EPA Victoria, Planning Victoria are all state-level). Council-specific timeframes and fees differ; that is why we publish per-council guides at /vic.
